Dual cold air intake?
we have one or 2 guys on the forum who have done a dual snorkel with stock parts, but I'm with crazy and the other guys on this. Running a cone under the hood isn't going to net you anything but hot air. The stock setup can be ram air type with the plate on the core support removed. If your really dead set on the looks of a dual, try doing something like this first.
What about this style CAI on a Grand Cherokee with the 5.9L it has a box in the front corner which I guess is where positive pressure is built under the hood. The only other option I was told about was sucking air from the HVAC box under the cowl since all cars have a cowl in front of the windshield for positive pressure reasons, basically the hose would be shorter then stock and reversed through a hole in the firewall.


Don't think you'd want to suck air from the same source as your HVAC system, you'll be fighting your fan for air the whole time.

I am not set on the looks, only thing about the looks that drives me nuts is from the outside having a hole only on one side of the radiator. Would a stock-part dual plastic tube setup like that have any advantage or would it work harder now splitting the air draw between two tubes??
You would think so but there is so much positive pressure there and the vents are so large on the cowl that there is more then enough air flow I think, I could be wrong.
uhhh...wow..umm yea that could potentially work pretty good if you dont mind cutting your core support a little for round tube holes, otherwise the stock magnum tubing would work. My 93' core support has the intake slot on each side making it symmetrical, if your core support has that too only thing you would have to do is relocate the battery a bit.

I don't see any advantage to a system like that on a stock engine other than looks. The engine will suck air slightly easier as it has twice the area to draw air from, but that is all dependant on if the intake tube is the restriction in your system, which it most likely isn't, that would be your throttle plate.
Where exactly are you thinking of cutting into? Do you mean the space that would be before the fan, and after the air inlet in your cowl? That isn't under positive pressure, it would be under negative pressure, as your fan is sucking air from that area. The part of your HVAC system that is under positive pressure would be after the fan but before your vents, but if you are thinking of using your blower for the HVAC system to push more air into the engine, I would strongly recommend that, as it won't work, you can't make it into a cheap turbo.

haha I am not thinking of using my fan as a an intake blower I was just talking about drawing from that same cowl box. I figured even half the cowl is enough for the fan to draw air from that with the fan on it would not affect my engine intake if it was linked with so many slots on the cowl.

Just another "throwing it out there" this is another reversed Jeep setup:
Here are the instruction to that really slick set-up you posted a picture of: https://dodgeforum.com/forum/1st-gen...r-cleaner.html
And thats not a reversed jeep setup its just the Ram box, my dads old 01' had the box on the left like that.
Nope no difference. At least none that I noticed. I did it strictly for appearances. I gained by switching to the 92-93 exhaust manifolds with a true 3" exhaust, 52mm throttle body, and the kegger mod.
Exactly they use a reversed style as the Jeep lol
